A carbon dioxide/volatile organic compound (VOC) transmitter, the Series CDTV, Model CDTV-2D4F4 lowers energy costs in buildings by adjusting the amount of conditioned air according to the occupancy of the space. The transmitter can identify vapors that might need to be expelled during times of lesser occupancy by detecting both CO2 and VOC.
